The JSON-vs-XML speed issue probably has to do with using the pure-Python simplejson library from contrib. In class Service, we should try to import the Python library json (2.6+), then simplejson (from the system, which might have the C optimizations) and only then fall back on contrib.simplejson. This would have to be done in gluon.serializers, too, and you want to make sure that the jsonrpclib is using the right json library.
